.CALK ATTACHMENT FOR HORSESHOES.

zen .of' the United States, residing at strnction. into which 2represents a corresponding Cyn'wyd, Montgomery county, State ofPennsylvania, have invented a new and useful Call: AttachinentforHorseshoes, of which the following is a specification.

My invention relates. to detachable calk attachments tor horseshoes, andit consists of improved means -forclamping the adjust able framecarrying the calks, to the shoe.

It further consists of improved means for adjustably clampingthe heelsor quarters of the shoe.

It further consists of improved'means for simultaneonsly moving theclamping members of the device.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth;

The annexed drawings and thefollowing descriptionset forth indetail, onemechani'- cal form embodying the invention; such detail constructionbeing but one of various mechanical forms in which the principle ofused.

the invention may he In said annexed drawings :Figure 1 represents,- aperspective view, seen from the undersideof a horseshoe and my improvedcall: attachment applied to the'same. Fig.

' bottom plan. view of parts of the attachment. Fig. 3 represents adetail view of one of the heel-clamps" Similar numerals of referenceindicate parts in the figures.

Referring to the drawings, the numeral 1 indicates a horseshoe oftheordinary con- The attachment has a plate, 2,- a toe-calk, 3, is secured,and said plate has upwardly and rearwardlyprojecting, inclinedtoe-clips, l, which-engage the the of the shoe and of the horses hoof.The

plate has two rearwardly extendi g arms, 5, connected at their rear endsby t bridgepiece, 6, which is formed with a longitudinal, screwthreadedbore, 7. One portion, 8, of a right and left screw, 9, fits to turn insaid bore and has a nut, 10, threaded upon it to serve as a lock-nut.The rear and oppositely screwthreaded en 11, of said screw is threadedinto a threaded bore, 12, of a yoke, 13,. and the flattened andperforated ends lt, of two screw-arm's, 15, are pi-v-- otally connected"to .the ends of the yoke upon pins, 16, and have clips, 17, upon theirSpecification of Letters Patent. Application filed October 6, 1911.

' so that it may have suiiicient Serial No.v 653,184.

HeeLcalks, 18, are secured in said clips. ,The.clips extend upward to engage the edges of the heels or quarters of the horseshoe. A washer, l9,anda nut, 20, fit upon each screw-arm to havethe washer bear againsttheinner edge of the heel or quarter. of the shoe, and the nut serves toclampthe washer shoe which is thus clam ed between the Washer and theupturned. l1p,'2l, of the clip.

he opening, 22, in the washer is of a somewhat greater diameter than thescrew-arm, play to find a square seat against the edge of the shoe. Thescrew has a polygonal end, 23, for the application of a key or wrenchfor turn-. ing it; s When the device is to he attaehed'to horseshoe, thescrew is rotated its forward end from the bridge-piece of the forwardplate and to force the yoke to outer ends.

which the screw-arms are pivots-Q, re: .ward,

and shoe of a horse,the clips will'be at the. shoe and, by rotating theoutside of said I right and left-screw, the bridge-piece and plate andthe yoke will be drawn together, drawing the clips in upon the outeredges of the shoe. When said parts tightened, the locl'onut upon theforward end of the ri ht and left screw is screwed up against theridge-piece, locking the screw against turning. The washers. are nowforced by'thenuts against the inner edges of the shoe," thereby firmlyclampin the heels or quarters of the shoe, and the time is sharp-shodwithout removal of the shoe. Byproviding the right and left screw to theyoke tor the heel-clips said clips will be evenly drawn together fromall sides at the same time, so that thedevice will have an even grip atall the shoe. he nuts and'wa'shers upon the screw-arms will clamp theheels of the shoe, thereby affording additional grip upon the 'shoe andinsuring firm attachment of the device upon the hoof and shoe. Othermodes of applying the principle of my invention may be employed for theagainst the edge of the to unscrew are sutliciently points of contactwith Patented Feb. 6, 1912..

engage the briogeepiec'e of the toe-clip and mode herein explained.Change may there- .fore be made as regards themechanism thus disclosed,providedZtt-he principles of construction set forth respectively in thefollowing claims are employed. I

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is z- 1. In a calk attachnient for horseshoes,a toe-plate provided with a toe-clip and'a toecalk; a screw rotatablyconnected to said plate, a yoke having a longitudinal threaded bore forsaid screw, screw-arms pivoted to said yoke and having heel-clips andheelcalks at their outer ends, and clamping nuts upon said arms.

2. In a calk attachment for horseshoes, a

toe-plate provided witlra toe-clip and a toecalk, a screw rotatablyconnected to said late, a yoke having a longitudinal threaded ore forsaid screw, screw-arms pivoted to said yoke and having heel-Clips andheelcalks at their outer ends, washers upon said arms and adapted tobear against the inner ed es of the. shoe, and nuts threaded upon t escrew-arms and bearing against said washers.
